Return Value

Returns an HRESULT value. Possible values include the following.

Value Description
S_OK Success.
E_NOTIMPL Method is not supported.
E_POINTER NULL pointer argument.


This method is intended primarily for seeking in media streams that might have excessive latency, such as streams being sent over a network. The returned values indicate cached data that has already arrived, which can be easily seeked. It is assumed that seeking to values beyond these returned parameters will cause a delay while the application waits for the data to arrive.

All time values are expressed in the current time format. The default time format is REFERENCE_TIME units (100 nanoseconds). To change time formats, use the IMediaSeeking::SetTimeFormat method.
